is anyone working on this? it has been a long time since the last post. now that i have new elements installed (HOORAY< I DID IT!!!) i need to fire those 20 bowls. some have the green underglaze on them and i have covered them in a different glaze this time. if it works, i will share that recipe.

i am sending out the recipe i found that works to cover amoco velvet green #353 and allows it to remain green. it is from George Wettlaufer's 1976 book, "getting into pots" and he describes it as having a waxy surface. the original recipe called for a feldspar called C-6, a soda spar. when i was unable to find any information on this product (even in the materials list posted on Digitalfire) i called mr. wettlaufer and asked what he would suggest to replace it. his reply was Kona F-4.

this covers colors nicely EXCEPT my mixed underglaze yellow which had floating chunks of yellow suspended above the clay and below the glaze which looked like someone threw yellow sand at a clear paint. unlike other glazes i have tested, this one does not "flatten" texture which is the most important quality for me. if you want to try it, test, test test.

have you been trying any of these glazes? i really wish i could send you a picture.

i was so pleased that 3 of the green underglazed pieces came out well enough to take to the empty bowl supper on friday. i approached one young man who had one of them and asked why he picked it out of the 400 bowls that were on offer. he said he liked the color. hooray! unfortunately, he dropped it on the driveway as he was leaving. we had some extra bowls and we gave him a green one from another potter so he at least had a green one.

I am so glad you found a solution. I am very busy getting glaze firings done for holiday shows. Wll pick up playtime in a couple of months. I wonder if the soda vs potash made the diff. There is also very little magnesium in the "good" glaze.
